Formula for the Length of the pipe.

AI Thread Summary
To find the length of a pipe open at both ends, the wavelength (λ) is calculated using the formula λ = v/f, where v is the speed of sound and f is the frequency. For a second overtone at 2000 Hz and a speed of sound at 343 m/s, the wavelength is determined to be approximately 0.17 m. The relationship between the wavelength and the length of the pipe is crucial, as the length of the pipe is typically a fraction of the wavelength. In this case, the user expresses uncertainty about the correctness of their calculation and plans to seek clarification from their teacher. Understanding the relationship between wavelength and pipe length is essential for solving such problems accurately.

Homework Statement


The second overtune for a pipe, open at both ends is 2000 Hz, the speed of the sound is 343 m/s. What is the length of the pipe?

Homework Equations


• λ = v/f

The Attempt at a Solution


λ = v/f = (340 m/s)/(2000 Hz) = 0.17 m
don't know if this is correct.
Thanks in advanced.

You found the wavelength of the sound. How is that related to the length of the pipe?
 
i don't know, it was in the problem given by our teacher. anyways, nvrmind my question, ill just asked him the correct answer.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
